This project will prove for once and for all if basketballs bounce higher with or without helium. Endnotes: The conservation of momentum is a very important concept in physics. This is most likely because the reading of the return bounce was not exactly correct and neither was the drop height. Ionic bonding is a crucial topic to understand within general chemistry reactions. This is the lab data explained. a. - Determine the energies involved for a free falling body The term Kinetic means an object in motion A Static object is one that is at rest (not moving). If you measure it in grams, simply divide the number by 1000 to get kilograms. an object in motion Kinetic object The hypothesis that if it the ball was dropped from a higher drop points, it would have a greater bounce height was supported. Vocabulary Words . On the Logger. We'll use a ball to measure potential energy and kinetic energy and examine how the energy is converted from one form to another as the ball falls from a high place. pellets, and briefly allow the excess water to drain from the pellets and strainer before CLEANUP : Leave the test tube with wax stuck in it in the lab station. c. Coil the wire around a pencil or other object, or fold the wire tightly to create a more 4 times more 4 times less Repeat Steps 68d for the The percent difference was calculated using the following formula. Momentum cannot be lost in a collision. Repeat steps 5 and 6 for KNO3. Record the equilibrium temperature in Table B. It can be proven that there were multiple sources of error by the slope of the equation on the Force vs. Acceleration group for this lab. releases or absorbs thermal energy by chemical processes. If you do not have . This will teach how to do momentum calculations for a variety of different situations where momentum is conserved - calculations that will illustrate the nature of momentum, and the fact that momentum is in fact conserved. Accuracy is how close the average of the measured values are to the actual value. To begin the lab a Vernier Dynamic Track was set up and leveled on a table. This button released the plunger, and propelled both carts down the track in opposite directions. copyright 2003-2023 Study.com. circle one and the calorimeter water. The energy of a moving object is called kinetic energy. 1 0 obj
